Subject: [PATCH 09/10] sh: remove SPARSEMEM related entries from Kconfig
Date: Mon, 13 Apr 2026 13:46:47 +0300 [thread overview]
Message-ID: <20260413104649.852228-10-rppt@kernel.org> (raw)
In-Reply-To: <20260413104649.852228-1-rppt@kernel.org>
From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>
Without NUMA support, SPARSEMEM related configuration options only create
unnecessary overhead.
Remove them.
